摘要
以GTM法设计的AC-16C改性沥青混合料为基础,在级配、油石比、粉油比变化的条件下,分别对混合料进行车辙、低温弯曲破坏、水稳定性和弯曲疲劳等试验。试验结果表明,对于沥青混合料的各项路用性能,4.75mm通过率、油石比、粉油比均存在一最佳值。研究结论对道路工作人员进行沥青混合料配合比设计和施工控制有指导意义。
There were different tests on AC-16C modified asphalt mixture designed by GTM under the changing conditions of gradation, asphalt-aggregate ratio and filler-bituminous ratio, including wheel tracking, low temperature bending failure, water stability and flexural fatigue tests, etc. The results showed that for different kinds of mixture service performance, the passing ratio of 4.75 mm, asphalt-aggregate ratio and filler-bituminous ratio all existed the optimum values. This conclusion was guiding significance in the asphalt mixture mix design and its construction controlling for the road staff.
